Comparing Exotic Cannabinoids: Delta-9 THC vs. Delta-8, Delta-10, HHC, HHCP, THC-O (THCOa), & THCP

Most people know Delta-9 THC, the famous and illicit cannabinoid simply called “THC.” However, only a few aficionados truly understand exotic cannabinoids like Delta-8 THC, Delta-10 THC, HHC, THCOa, and THCP. 

These novel cannabinoids are all psychoactive, and some exist naturally in hemp and cannabis plants, like Delta-9. However, most exotic cannabinoids are synthetically made and have unique qualities that customers need to understand. The main difference between exotic cannabinoids and Delta-9 THC is their molecular structures, psychoactive intensity, and legality.

Here we compare today’s top trending exotic cannabinoids so consumers can make the most informed decisions.

What Is Delta-8 THC?

Delta-8 THC is a natural exotic cannabinoid found in cannabis and hemp plants in trace amounts. It produces psychoactive effects like Delta-9 THC but with unique qualities. 

Delta-8 THC Experience

Delta-8 produces a mild psychoactive experience that users describe as calming and euphoric. Delta-8 can reduce feelings of nausea and provides many known benefits of THC. In one study, 71% of Delta-8 users reported relaxation, 68% experienced euphoria, and more than 50% got relief from pain. 

Delta-8 compared to Delta-9

Delta-8 appears to have a lower affinity for the brain’s CB1 receptor, making it less potent than Delta-9 THC. Most consumers say Delta-8 is noticeably milder than Delta-9 and has an “indica-like” high due to its sedative properties. Its lower potency also means Delta-8 is less likely to cause adverse effects, such as paranoia.

Molecular Structure

Delta-8 and Delta-9 have the same molecular formula with different atomic arrangements, making them both “THC isomers.” Both exotic cannabinoids contain a double-carbon bond but on different atom chains. In Delta-8, the double carbon bond falls on the 8th atom chain, while Delta-9’s falls on the 9th—hence the names. Scientists believe this difference partly explains Delta-8’s effects and potency variation.

Cannabinoid Type: THC isomer

How Delta-8 Products Are Made

Delta-8 occurs naturally in cannabis but in minimal amounts. As a result, most Delta-8 products are synthesized CBD. Processors extract CBD from hemp and convert it into Delta-8 THC using a blend of chemical solvents (like heptane) and acids (like hydrochloric) in a process called “isomerization.”

Delta-8 Hemp and Cannabis Products

Delta-8 is one of the fastest-growing compounds on the hemp market. It’s available in many cannabis and hemp-based products that consumers can inhale, ingest, and apply topically, including:

  • Distillate cartridges
  • Distillate syringes
  • Vape cartridges
  • Tinctures
  • Oils
  • Concentrates
  • Gummies and edibles
  • Beverages
  • Flower (sprayed with Delta-8 distillate)

Delta-8 Legality: Updated October 2022

Delta-8 is federally legal. However, due to its production methods and lack of comprehensive legislation, many states have introduced bills that explicitly prohibit Delta-8 and other exotic cannabinoids made through isomerization. So far, 17 states, including Colorado, Washington, New York, and Michigan, have banned Delta-8. Check out our State-by-State Delta-8 Legality Guide for the latest updates. 

What Is Delta-10 THC?

Delta-10 THC is a natural minor cannabinoid found in cannabis and hemp plants in trace amounts. Its effects tend to be more energizing and less potent than other THC isomers. 

Delta-10 THC Experience

Delta-10 users report an uplifting and energizing experience with a gentle head buzz. Reddit users claim similar effects to Delta-8 THC, albeit less potent, likening Delta-10 to a Sativa strain’s “mind high” instead of a physical body high. Many describe Delta-10 as a great daytime product that enhances motivation, creativity, and cognitive function. 

Delta-10 compared to Delta-9

Delta-10 is less potent than Delta-9, likely due to a weaker binding affinity to receptors in the endocannabinoid system. Delta-10 offers euphoria and increased focus with buzzy, energizing qualities similar to a Sativa strain but without the paranoia and anxiety some users report from Delta-9.

Molecular Structure

Delta-10 and Delta-9 have nearly identical chemical structures with double carbon atom rings. However, that bond occurs on the 9th atom ring in Delta-9 and on the 10th ring in Delta-10, hence their respective names. This atomic similarity makes Delta-10 a THC isomer. 

Molecule Type: THC isomer 

How Delta-10 Products Are Made

Delta-10, like Delta-8, appears in trace quantities in cannabis plants. As a result, manufacturers can’t extract enough to make products. So they utilize an isomerization process similar to Delta-8. Here’s how it works: Producers usually extract hemp-derived CBD using chemical solvents and convert the CBD into Delta-10 using solvents and acids. 

Delta-10 Hemp and Cannabis Products

Delta-10 products are increasingly popular, and many product types are on the market for users to vape and ingest. Delta-10 cannabis and hemp-derived products include

  • Disposable pens
  • Vape cartridges
  • Gummies
  • Tinctures and oils 
  • Dabbing syringes
  • Chocolate bars
  • Lollipops
  • Shatter 
  • Flower and pre-rolls (sprayed with Delta-10 distillate)

Delta-10 Legality

Delta-10 products are federally legal under the 2018 Farm Bill if sourced from hemp containing less than 0.3% Delta-9 THC. Currently, Delta-10 THC is legal in most states. However, as with Delta-8, some states have outlawed Delta-10, so customers need to check local laws before purchasing these products. 

Comparing Delta 10 to Delta 8 and Delta 9 THC Molecules

What Is HHC?

HHC (hexahydrocannabinol) is a hydrogenated derivative of Delta-9 THC. It is a naturally occurring phytocannabinoid found in cannabis in trace amounts that is usually made synthetically from cannabis extracts via a “hydrogenation” process. 

HHC Experience

HHC users report a gradual, euphoric high followed by a smooth, calming experience. Many say it produces a less energetic high than typical sativas and is more cerebral and other-worldly. 

HHC compared to Delta-9: Consumers observe that HHC induces less-potent psychoactive effects than conventional Delta-9 THC. Still, some say HHC lasts much longer than Delta-9 (up to 12 hours).

Molecular Structure

HHC is not a tetrahydrocannabinol like Delta-8, Delta-9, or Delta-10. HHC belongs to a different chemical class known as hexahydrocannabinol. HHC has no double carbon bonds and includes hydrogen molecules instead. The hydrogen molecules in HHC also make it more stable, allowing HHC products to withstand oxidation, heat, and ultraviolet light better than THC.

Molecule Type: Hydrogenated derivative of THC. Also considered a THC analog compound.

How HHC Products Are Made

HHC is not abundant in the hemp plant, so producing it often involves transforming other compounds. Most HHC is made from Delta-8 THC through a process called hydrogenation. Producers start with CBD, which they convert to Delta-8. Then they use two active catalysts (typically heavy metals) to break apart Delta-8’s double-atom bonds and insert two hydrogen atoms, converting THC to HHC. 

HHC Hemp and Cannabis Products

HHC is a recent entry into the hemp market, so fewer product offerings exist. Two common HHC product types on the market currently include 

  • Edibles 
  • Vape cartridges

HHC Legality

HHC is federally legal because it is a hemp derivative covered under the 2018 Farm Bill. However, as state and federal agencies continue to ban Delta-8 THC and other synthetic cannabinoids, some have also banned analogs like HHC

What Is THCOa (also called THCO)?

THCOa, often called THCO, is a federally legal exotic cannabinoid that users report is three times as potent as Delta-9. However, unlike Delta-9, Delta-8, Delta-10, and HHC, THC-O acetate does not naturally occur in hemp or cannabis plants. Manufacturers must synthesize hemp-derived compounds in a lab to create this THC analog.  

THCO Experience

THCO is an incredibly potent cannabinoid that produces intense euphoria and viscerally relaxing effects. Many consider THCO more of an evening substance because of its physically sedating properties. In larger doses, some say THC-O can be borderline psychedelic with potent couch-lock effects. 

THCOa compared to Delta-9

THCO is a more potent analog of Delta-9 THC, meaning its psychedelic effects can be more intense. It takes longer to kick in, but the consensus says that THC-O is around three times more potent than traditional Delta-9 THC. Some claims suggest that THC-O is more bioavailable than other forms of THC, meaning more THC-O makes it to the bloodstream. 

Molecular Structure

THC-O shares the same base structure as Delta-9 THC and other cannabinoids found in nature. However, THC-O is an acetylated version of THC created by taking Delta-9 and binding it with acetate (a salt formed from acetic acid) using various chemicals. Acetylation allows THCO to cross lipid-sensitive layers in the digestive tract and brain more easily.

Molecule Type: Acetylated derivative of THC. Also considered a THC analog. 

How THC-O Products Are Made

Manufacturers synthesize THC-O through a chemical process. First, they start with hemp-derived Delta-8 or Delta-9 THC. Then they combine the THC molecules with acetic anhydride, a high-inflammable and colorless liquid used to make fibers, plastics, pharmaceuticals, and dyes. This process acetylation process converts Delta-8 to THC-O. 

THC-O Hemp and Cannabis Products

THC-O is a relatively recent cannabinoid to hit the market. Most THC-O products feature a blend of other hemp-derived cannabinoids and mainly include: 

  • Vape cartridges
  • Gummies
  • Distillate

THC-O Legality

THC-O is federally legal under the 2018 Farm Bill and available in most states. However, like other THC analogs, THC-O is banned in certain states.

What Is THCP?

THCP (tetrahydrocannabiphorol) is a naturally occurring phytocannabinoid and THC analog found in hemp and cannabis. A research project recently discovered THCP by accident in 2019 and found a 30x higher CB1 binding affinity than Delta-9. This discovery suggests THCP could have significantly more potent effects.  

THCP Experience

THCP is the most potent naturally occurring THC analog available today. While there isn’t much information surrounding THCP and how it feels, the few people who have tried it say the effects are similar to Delta-9 THC, only much stronger and more stimulating. People even describe the THCP experience as “psychedelic-like,” saying it can amplify sounds and colors, an uncommon effect with traditional THC. 

THCP compared to Delta-9

The few who have tried THCP suggest its effects were 5 to 10 times stronger than regular Delta-9 THC. 

Molecular Structure

THCP has a similar molecular structure as THC isomers like Delta-9, Delta-9, and Delta-10. However, these THC isomers have five carbon atoms on their alkyl side chains, while THCP contains a seven-atom side chain. According to the Italian report, the two additional atoms might explain THCP’s stronger binding affinity and effects. 

Molecule Type: THC homolog 

How THCP Products Are Made

THCP naturally occurs in cannabis plants, but only in small concentrations. As a result, most producers manufacture THCP products in a lab by chemically manipulating CBD extracted from hemp plants.

THCP Hemp and Cannabis Products

Few THCP products exist on the market, but THCP uses are the same as other cannabinoids. Available THC-O products include:

  • Tinctures
  • Distillate
  • Vape cartridges 
  • Gummies

THCP Legality

THCP is federally legal under the Farm Bill when derived from hemp plants. No state bills specifically ban THCP, but it is illegal in states that prohibit all forms of THC.


HHCP (hexahydrocannabiphorol)  is a very rare and powerful exotic cannabinoid. It is the hydrogenated counterpart of THCP and structurally similar to Delta-9 THC’s hydrogenated counterpart, HHC. 

HHCP is gaining popularity due to its molecular structure, making it feel ten times more potent than Delta-9.

HHCP Experience

Users indicate that the HHCP experience feels like THCP, the strongest cannabinoid on the market, but with longer-lasting effects. As a result, HHCP feels significantly more powerful and euphoric than Delta-9 THC, capable of causing an extended period of blissful sedation.

Molecular Structure

HHCP has the same structure as HHC but with two more carbons in its alkaline chain than HHC. Researchers believe HHCP’s additional carbons increase its ability to bind with cannabinoid receptors in the brain and nervous system. As a result, HHCP will produce a stronger psychoactive effect. 

How HHCP Products Are Made

HHCP products are not natural. Manufacturers produce this exotic cannabinoid by extracting CBD from hemp and converting it into the final cannabinoid form through a series of chemical processes. Consumers should only purchase HHCP from reputable brands that test these products against the highest safety and quality standards.

HHCP Products

HHCP is a new cannabinoid, so most manufacturers don’t make it yet. However, consumers can still find HHCP disposable vapes, cartridges, dabs, concentrates, and even flowers sprayed with HHCP distillate. 

HHCP Legality

HHCP is a federally legal hemp derivative. That said, consumers should check local laws surrounding exotic cannabinoids as several states, from Delaware to Washington, placed bans and limits on psychoactive hemp derivative products. 

Key Differences between Delta-9, Delta-8, Delta-10, HHC, THC-O, THCP, and HHCP

One of the key differences between these compounds is how they’re made. Unlike Delta-9 THC, which occurs naturally in large quantities and is extracted directly from the plant to make various products, Delta-8, Delta-10, HHC, THC-O, THCP, and HHCP are extremely rare or non-existent in the plant. As a result, these analogs and homologs are commonly made by chemically altering hemp-derived CBD using various catalysts. 

Legality is another crucial area of distinction. While Delta-9 THC is a Schedule I controlled substance, hemp-derived THC compounds are federally legal under the Farm Bill. 

A few more notable differences from Delta-9 THC include:

  • Delta-8, Delta-10, and HHC are less potent than Delta-9.
  • THCO, HHCP, and THCP are considerably more powerful. 
  • Delta-8, HHC, and HHCP are more calming, with sedative “indica-like” qualities. 
  • Delta-10 and THCP are more stimulating, with energizing “Sativa-like” qualities.
  • All have slight differences in their atomic or molecular structures that contribute to their unique effects. 

Key Similarities

Delta-9 THC, Delta-8, Delta-10, HHC, THC-O, THCP, and HHCP all exhibit psychoactive effects in some form. A few more notable similarities include the following:

  • Delta-8, Delta-10, HHC, THC-O, and THCP are all derived from hemp. 
  • All appear to interact with cannabinoid receptors in the body to produce therapeutic effects, such as euphoria, relaxation, and pain relief. 
  • These compounds are available in many similar product forms, including flowers, gummies, tinctures, and vapes. 
  • All THC isomers and homologs will appear on a standard drug test. HHC and HHCP may not be because they’re different compounds, but more research is needed to confirm that assumption. 

The Bottom Line

Delta-9 is the most well-researched and well-understood psychoactive compound. Still, recent hemp industry innovations show Delta-9 may not be the most potent or desired product. Customers may prefer exotic cannabinoids due to their experience profiles, legality, and product types. 

Regardless of the cannabinoid choice, all customers must look for hemp brands that publish a Certificate of Analysis (COA) featuring their product’s safety and potency test results. Additionally, all exotic cannabinoids must be tested for manufacturing chemicals, such as solvents, acids, and metals.
